HOW TO INCREASE OUR SUSTENANCE OR WEALTH. 
ALLAH the Almighty says:
“ And remember when your Lord proclaimed, ‘if you are grateful, I will certainly give you more. But if you are ungrateful, surely My punishment is severe.” (Quran, 14:7).
ALLAH promises us in this beautiful verse to give us more if we are grateful. Showing gratefulness to ALLAH is not done simply by saying Alhamdulillah, but it is also by using what ALLAH gave you in the manner HE is pleased with by offering some to relatives and the needy instead of lying you don't have it.
When you appreciate the little you have then offer some in sadaqah to others then be sure that ALLAH will give you more. You can say Alhamdulillah 1000times a day but if you don't support the needy, your relatives and the work of ALLAH, you may even fall into HIS punishment due to your ungratefulness. Those who are ungrateful and uses the blessings of ALLAH in a haram way. ALLAH warns such people with a severe punishment. May ALLAH keeps guiding us all and protect us from any satanic influences. Aameen.
